Definitions

  • This invention relates to a wind deflector for preventing the build-up of snow and ice on the back of snowplow trucks or other vehicles.
  • snowplow trucks are commonly equipped with an enormous array of bright flashing lights and reflectors.
  • the vertical back wall of the plow is typically provided with a reflective warning pattern, such as a black and yellow checkerboard pattern.
  • the invention involves a forwardly-opening scoop positioned at the upper rear of the vehicle to collect air, and a downwardly directed duct portion communicating with it to direct air downwardly along the vertical rear wall of the truck.
  • the device has multiple air outlets, to distribute the air to different areas, to maximize the cleaning effect.
  • the device extends down to cover the full height of the rear of the truck, with air outlets near the bottom thereof so that tail lights are also washed by air.
  • a reflective checkerboard is displayed on the device itself.
  • FIG. 1 is a perspective view of a typical snowplow truck, from the rear quarter, with the preferred embodiment of the invention installed;
  • FIG. 2 is a perspective view of the preferred embodiment
  • FIG. 3 is a side elevation view of the preferred embodiment, in cross-section, installed on the rear wall of the snowplow truck;
  • FIG. 4 is a side view of the snowplow truck, showing the method of installation of the preferred embodiment.
  • FIG. 5 is a rear view of the snowplow truck with the preferred embodiment installed.
  • FIG. 1 of the drawings a typical snowplow truck 1 is shown.
  • the truck carries a snowplow in front of it (not shown), and has a truck box 4, including a generally vertical rear wall 6 and tail/brake lights 8.
  • the device 10 of the invention involves a forwardly-opening scoop 12 positioned at the upper rear of the vehicle, to collect air and direct it downwardly along the wall.
  • the device extends down to cover the full height of the rear wall 6. Since that means covering the reflective checkerboard on the truck box, the device itself preferably is provided with a reflective checkerboard 14.
  • the device has multiple air outlets, to distribute the air to different areas, to maximize the cleaning effect by ensuring that there are generally no significant "dead" areas against the wall.
  • a small portion of the air is picked up by the interior channel 21, to flow down the length of the device to wash the tail/brake light area, via lower outlet slot 20.
  • the device may be secured to the rear wall 6 by any suitable means. In the preferred embodiment, as one example, it has a downwardly-projecting lip 22 which fits over the top of the wall. The lower portion of the device is then bolted to the wall or frame elements thereof. To avoid deformation of the outer wall towards the inner wall, the device may be molded such that the outer wall projects inwardly against the inner wall in the area of the bolts. Alternatively, spacer sleeves could be used around the bolts.
  • a number of bolt locations 24 can be provided, with the correct ones for the job being selected at the time of installation.
  • the preferred embodiment lends itself readily to manufacture via rotational molding.
  • the device is molded to its finished external shape and then the various openings, namely the scoop 12 and the outlets 16, 18, and 20 are cut through the plastic, using a router or any other desired cutting means.
  • outlets are not essential to the invention. There could be more outlets or fewer outlets, as desired. Multiple outlets are obviously preferable, however, and the configuration of the preferred embodiment is considered optimal.
